ABSTRACT

A hand support device and method for somatosensory input to the palm comprises a support portion and an attachment portion. The support portion forms a rounded surface that supports a hand of a user. The attachment portion attaches to a structure. The device activates purposeful motor movement with accurate motor control for users with Dyspraxia when employed in conjunction with evidence-based developmental pedagogy in high stimulating tasks such as music education per the Rancer Method (Kupferstein &amp; Walsh, 2015). In one example, the hand support device attaches to a piano and clamps to the keyslip allowing the user to rest their hand while playing the piano. In another example, the hand support device is adapted to attach to a surface of a laptop or desk with a base surface that is disposed above the laptop, allowing the user to rest their hand while typing on the keyboard.

TECHNICAL FIELD

The described embodiments relate generally to support methods, and more particularly to hand support devices directed to motor control disorders.

BACKGROUND INFORMATION

Motor planning disorder is a condition often associated with dyspraxia, autism, and other neurodevelopment disorders. Motor planning dysfunction prevents a person from having accurate motor movements as compared to typically developed individuals. As a result, physical assistance is required from caregivers. Unfortunately, caregiver dependence may prevent people with dyspraxia from independently executing tasks that require fine and gross motor movements. Evidence based methodologies are desired to remediate these challenges.

SUMMARY

A hand support device comprises a support portion and an attachment portion. The support portion forms a rounded surface that supports a hand of a user. The attachment portion attaches to a structure, such as a piano or a laptop. The hand support device is adapted to be used for people with dyspraxia. When the hand is placed above the support portion, the weight of the hand causes the support portion to apply pressure onto a center of the palm. By applying specific pressure into the center of the palm, bones on the top of the hand shift to activate the muscles in between the hand bones, which are then available to receive signals from the brain to complete the motor plan. In this fashion, the applied force creates a synthetic shoulder for gross-to-fine translation. When independent finger isolations emerge, the need for the applied force will subside. In accordance with one novel aspect, neuroplastic changes in the motor systems of the user with dyspraxia will habituate movement through muscle memory for the completion of complex tasks such as playing the piano or typing on a keyboard without needing the hand support device.

In one embodiment, the hand support device is adapted to attach to a piano. The attachment portion of the device has a clamping mechanism that clamps onto the ledge of the piano keyslip allowing the user to rest their hand on the device while playing the piano. The clamping mechanism has a tail having a hole, a fastening element that extends through the hole, and a ledge that extends downward from the base of the support portion. A user attaches the clamping mechanism to the keyslip of the piano and tightens the fastening element until the hand support device is securely attached to the piano. The attachment portion contacts the structure along at least three surfaces. Next, the user places his/her hand above the hand support device and may play the piano keys with his/her fingers.

In another embodiment, the hand support device is adapted to attach to a surface of a laptop or desk. The attachment portion of the device has a base that has a planar surface. The planar surface is adapted to be disposed above a flat surface of a structure. A user places the support device above the laptop surface below the keyboard. The attachment portion contacts the structure at a single surface. Next, the user places his/her hand above the hand support device and may type on the keyboard with his/her fingers.

The foregoing is a summary and thus contains, by necessity, simplifications, generalizations and omissions of detail; consequently it is appreciated that the summary is illustrative only. Still other methods, and structures and details are set forth in the detailed description below. This summary does not purport to define the invention. The invention is defined by the claims.
